Delta Air Lines cancelled nearly 250 Tuesday flights as the company works to "reset" its operations after a computer outage grounded flights worldwide.
The Atlanta-based carrier, one of the world's largest, said those US-morning cancellations come as it works to get aircraft and crews to where they are supposed to be.
The company indicated that more schedule changes may be coming.
"We were able to bring our systems back on line and resume flights within a few hours yesterday but we are still operating in recovery mode," Dave Holtz, of Delta's Operations and Customer Center, said in a statement.
"We are doing everything we can to return our operation to normal reliability, but we do expect additional delays and cancellations," he added.
A power outage at a facility in Atlanta crippled the airline's global computer systems for several hours on Monday, leading to the cancellation of about 1,000 flights and stranding passengers at airports around the world.
